My husband and I pinch pennies wherever we can. So when he wanted a high definition television we had to find a loop hole. So here is how we did it. My husband shopped around for televisions, he liked Samsung the most. We bought it on Amazon so we wouldn't have to pay tax, they also delivered it and set it up.
Then we bought an antenna that received high definition and plugged it into our TIVO. We hooked the antenna onto our roof. Now we get free HD. We get all the major stations, PBS, NBC, ABC and CBS. You need to make sure you have a tuner to hook the antenna into, I don't think you can plug it directly into the television.
Our antenna looks something like this one, it's not too big.
